Imported type overrides local value declaration, yielding undefined

[Oblosys]

TypeScript Version: 2.3.3, nightly (2.4.0-dev.20170525)

Code

// Main.ts:
import { X } from './Types'
const X = 42;
console.log('X is ' + X);

// Types.ts:
export type X = {}

Expected behavior:
Output: X is 42
Actual behavior:
Output: X is undefined
The value reference X is transpiled to the undefined Types_1.X instead of just X. Declaring type X = {} in Main.ts instead of importing it works correctly.

Much appreciated!
